Vegetative propagation in mint occurs by

Options

A. Rhizome
B. Sucker
C. Runner
D. Offset

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the method of vegetative propagation in mint. We need to identify the correct stem modification that allows mint to propagate vegetatively.

2. **Identifying the Options**: The options given are:
- Rhizome
- Succor
- Runner
- Offset

3. **Analyzing Each Option**:
- **Rhizome**: This is a horizontal underground stem that helps in vegetative propagation in plants like turmeric and ginger. Since mint does not primarily use rhizomes for propagation, this option is incorrect.

- **Succor**: This is a sub-aerial stem that arises from the basal underground part of the main stem. It grows horizontally under the soil for a distance and then emerges obliquely upward. This structure develops a leafy shoot and roots before separating from the mother plant. This is the correct method of vegetative propagation in mint.

- **Runner**: Runners are also sub-aerial stems but are typically associated with plants like grasses. They do not play a significant role in mint propagation, making this option incorrect.

- **Offset**: Offsets are another type of sub-aerial stem modification found in plants like water hyacinth. This is not the method used by mint for vegetative propagation, so this option is also incorrect.

4. **Conclusion**: After analyzing all the options, the correct answer for the method of vegetative propagation in mint is **Succor**.

**Final Answer**: Succor
